ELIAS C. GLAZIER, OF ROCHESTER, NE\V YORK, ASSIGNOR TO THE STEAM GAUGEAND LANTERN COMPANY, OF SAME PLACE.

TUBULAR SPECIFICATION forming part of Letters LANTERN.

Patent No. 391,240, dated October 16, 1888.

Application filed February 2. 1888. Serial No. 262,710. (No model.)

To all whom it may concern.-

Be it known that I, ELIAS O. GLAZIER, of Rochester, in the county ofMonroe and State of New York, have invented new and useful Improvementsin Tubular Lanterns, of which the following is a specification.

This invention relates to that class of lamps or lanterns which containa tubular frame, in the lower portion of which the oil-pot and burnerare supported, and in which the globe is loosely arranged, so that theglobe can'be raised from the burner when access is required to thelatter for adjusting the wick, lighting and extinguishing the lamp, andfor other manipulations.

The object of my invention is to provide the lamp with a simple andconvenient device for raising the globe and holding it in an elevatedposition.

The invention consists of the improvements which will be hereinafterfully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation of alamp provided with my improvements. Fig. 2 is a fragmentary sideelevation of the globe-lifting device on an enlarged scale. Fig. 3 is ahorizontal section in line w 00, Fig. 1. Fig. at is a side elevation ofa modified construction of the globe-lifting device on a reduced scale.

Like letters of reference refer to like parts in the several figures.

The lamp illustrated in the drawings, to which my improvements areapplied, is a tubular globe street-lamp, the general construction ofwhich is well known, and which is described and shown, for instance, inLet ters Patent No. 218,917, granted to Lewis F. Betts, August 26, 1879.

A represents the post socket at the base of the lamp-frame; B B, theair-tubes; C, the lamp-top; D,the removable air-chambenwhioh inclosesthe oil-pot d, and E the globe. The latter can be raised in thelamp'frame, so that the burner can be exposed and the airchamber D beremoved from the lamp-frame with the oil-pot and burner, if required.All of these parts are old and well known.

F represents alifting bar or frame arranged on the inner side of one ofthe air-tubes B B, and sliding vertically in loops or eyes ff, se-

cured to the inner side of the air-tube. The lifting-bar F isprovidedwith a hook or globesupport, G, in which the globe rests, and which isformed on or secured to an arm or lateral eX- 5 tension, 9, formed onthe liftingbar F. The lifting-bar F is provided above the arm 9 with anose or projection, g, which engages over the upper edge of the upperloop, f, when the lifting-bar is raised, and thereby holds the lat- 6otor and the globe in an elevated position, as shown in Fig. 2.

it represents a flat spring secured to the inner side of the airtube, towhich the liftingbar is attached, and bearing with its lower 6 free endagainst the upper rear side of the lifting-bar, so as to force the upperportion of the latter outwardly toward the globe and re tain its nose 9in engagement with the loopf. Upon pushing thelifting bar inwardlyagainst the pressure of the spring h until the nose 9 clears the upperedge of the loop f, theliftingbar with the globe can be lowered. Theupper loop, f, is made large enough to permit of the requisite lateralplay of the upper portion of the lifting-bar. The arm or extension gforms a stop, which prevents the lifting-bar from being raised so far asto withdraw its lower end from the lower loop, f. A ring or loop, 1', ispreferably arranged on the under side of the arm 9, in which the thumbis inserted, and a finger-piece, i, is secured to the outer side of theadjacent air-tube above the upper loop. f, so that the lifting-bar canbe easily raised. As the lifting-bar is guided in 8 the loopsff and theglobe is attached to the lifting-bar, the globe is properly seated uponthe air-chamber upon depressing the liftingbar without any effort orattention on the part of the attendant. I

In the modified construction of the globe lifting device represented inFig. 5 the spring is omitted and the locking-nose g is formed on therear side of the lifting-bar and held in engagement with the lowerguide-loop by the 5 overhanging weight of the globe when the latter israised.

I claim as my invention- 1. The combination, with the lamp or Ianternframe provided with loops or guides and IO( the verticaily'movableglobe, of an upright lifting-bar sliding in said loops or guides and Iprovided with a globe-support and with a lock- 1 bar and the globe in anelevated position, and

ing nose or projection which engages over one of said loops or guidesand holds the liftingbar and the globe in an elevated position,substantially as set forth.

2. The combination, with the lamp or lana spring attached to the lamp orlantern frame bearing against the lifting-bar and holding the 15 nose orprojection thereof in engagement with Witness my hand this 27th day ofJanuary,
